familia engine

[DrPhill]

is their 2000cc the same engine as our 2.0?

 

[jsgolfer]

im not an expert but i think the J-spec famillia you speak of comes with the stronger FS-ZE engine. i believe it is rated at 170hp. same displacement i believe but more power. it has different cams, intake, ecu, and maybe pistons aswell. hope that helped

 

[DrPhill]

does a normal p5 handel better than a wrx? or 2.5 impreza(normal)?

 

[jsgolfer]

it has better skid pad but im not sure about slalom. and i am sure it out brakes the wrx

 

[DrPhill]

what is a skid pad?

 

[Stealth5]

omg, dont ask questions if you dont even know what a skidpad is....its a large cement area thats used to test cars grip in G-Forces...the p5 does have better grip, especially with new tires. i believe it also does the slalom faster, but the WRX would win in a race.... it has 97 more HP

what is a skid pad?

Just driving the car in a circle and seeing how much lateral force it creates. Measured with Gs. You can't really determine handling from skidpad alone.

Handling is something that can't really be measured by numbers either, but I think if you took both cars through a bunch of cones and twisties they would be pretty equal. According to R&T the MP3 is one of the best handling cars out on the market (at the time) so I'm guessing the P5 would be pretty close if not better than a WRX at cornering, only problem is the WRX is turbo charged so they'd probably win any race a stock P5 took at him. And I don't know anything about the non turbocharged WRX.

ONLY if you let him get you in the straights.....keep it in the twisties....and you have an even chance of taking him.

A stock WRX would beat the crap out of a a stock P5 in a race, a non turbocharged Imprezza vs a P5...hmm, now that sounds like a fair challenge.

 

[pr5owner]

a Famila w/ 170 HP Vs a 2.5RS w/ 165HP,both having AWD and both weighing about the same, i saw the famila would win, but not by much

BTW, the J-spec FS-ZE have a higher compression ratio then the FS-DE we have, the difference, I believe, is 10.5:1 vs 9.5:1 respectively, correct me if I'm wrong please....

FS-ZE also benefit from an agressive intake cam, intake manifold and a ODB-I ECU with less restrictive emission control and a different air-fuel map than out ODB-II ECU.

I myself is planning to do the conversion just like that, but with the APEXi S-AFC to give me the modified fuel map as well as a ported head to support the new piston set and a less restrictive exhaust system...

oh yes, did I mention a Mazdaspeed exhaust cam and adjustable cam gears as well?

i dont know about the FS-ZE but the FS-DE have 9.1:1 compression
why no turbo??

 

[REMillers]

make sure you work on wiring in the ODB-I. Someone here recently did a JZ swap using the ODB-II and think it made same power as the MP3.
Crappy emissions controls. Funny car may run "cleaner" but ends up using more fuel. hmpf.

 

[mopiko]

Thanks for the correction, yes it is 9.1:1 US spec and I'm pretty sure the ZE is in the 10:1 range....

Why no turbo? Because I'm trying to see how much hp I can squeeze out in a all-motor set up, our 2.0L has some potential and I hate to see it only crack 130, I want to maximize it's potential and see how much I can do.

I am thinking turbo too, but then I'll be running a lower compression ratio and port and polish the head this time as well as keeping the stock intake cam and a 3" exhaust set up. It's a completely different approach but I'm leaning towards the all motor set up at this time.

Any comments or suggestions?

 

[perfworks]

just with your stock set up you will make more HP with a 8 psi turbo kit than you will ever make with a ton of N/A mods
just a thought , dont take it the wrong way.

 

[mopiko]

Yes I agree, but my concern will be the reliability of the turbo set up in the long run, don't know if the valves and valve springs will take 8 psi boost.



and don't worry I'm not taking it the wrong way, like I said all suggestions are welcome.

8 psi no problem.
but even N/A reliabilty with the valve springs become an issue when you increase the resistance

 

[mopiko]

hummm.... True true true....Who is offering the 8 psi system you mentioned? Let me take a look

 

[perfworks]

i will be in about a week. when i finish and have dyno results.
you can come to the run since your right around the corner. take a look at the setup and let me know
i pmed you my number. give me a call and we can talk about it.
